My 6 year old has been learning about trees at school, and had questions for me. Needless to say, she now has the best understanding of data structures in her class, and I expect parents evening will be "interesting"8

You are good in programming and data structures.
But we won't select you because you couldn't solve the puzzle. 😑11 -

Biggest scaling challenge?
The imaginary scaling issues from clients.
Client : How do you cope with data that's a billion times bigger than our current data set? Can you handle that? How much longer will it take to access some data then?
I could then give a speech about optimizing internal data structures and access algorithms that work with O(log n) complexity, but that wouldn't help, non-tech people will not understand that.
And telling someone, the system will be outdated and hopefully been replaced when that amount of data is reached, would be misinterpreted as "Our system can not handle it".
So the usual answer is: "No problem, our algorithms are optimized so they can handle any amount of data"6 -
At my old company one of my colleagues introduced async / await into our csharp code. He created interfaces and showed us a great structuring of his code. Sadly a few weeks later he left the company, because of personal reasons and a bug appeared in his written service. Our senior developer took the issue and complained for like 1 week. That you can't find anything, that interfaces are useless, that async / await is slow and sucks and that we should stop trying to bring new structures into the code base and do things the old way. In the end he deleted all the great things that my colleague introduced and wrote bad and smelly code.9

Was recently phone interviewed by a recruiter that asked "So do you know data structures and algorithms?" I replied "That's like asking someone if they know Mathematics - can you be a bit more specific?"7

How to land a programming job
1. ABC (Always Be Coding) - The more you code, the better you'll get.
2. Master at least one multi-paradigm language - Some good candidates are C#, C++, Java, PHP, Python, and Ruby.
3. Re-invent the wheel - You should implement the most common data structures in your language choice.
4. Solve word problems - Pick those that test your ability to implement recursive, pattern-matching, greedy, dynamic programming, and graph problems
5. Make coding easy - At least, make it look easy.
6. Be passionate - If you don't care, then nobody else will.
7. Don't make assumptions - Ask questions if you're not sure.11 -
Our Algorithms and Data Structures lecturer would have died on the spot if you showed him code like that...

Once upon a time while browsing his Instagram, a young and inexperienced boy found a magic realm called devRant.
He decided to hop on the cyberweb of interconected computers, aka. the Internet and found the gate to the magic realm.
Timidly he took a step forward and found himself surrounded by strange structures called Rants and Stories.
No knowing what to do, he now roams in this new and strange realm looking for some guidence and perhaps even friendship.26 -
I want to thank every Indian computer scientist on Youtube. Because of these guys I passed my Algorithms and Data Structures Exam.10

True fact!
Had my practical exam yesterday on Data Structures using C.
Had included this in my code
if(!count)
break;
Examiner: What type is count?
Me: Sir, it's an integer.
Then he asked me what was not expected.
Examiner: What does this exclamatory mark do?
In my mind: Now's the right time for the world to end. 😛9 -
Fuck project setups that
- Have huge nested enterprise folder structures like Java
- Use tons of shell scripts / makefiles
- Have every config file in the root folder
- Don't tell me what I need / how to build
I know some of these can't really be changed easily, but fuck this cluttery mess!25 -

Let's see the coder in you.
If I give input: 1 output: 2
If I give input: 2 output:1
Only these two test cases needed.
You should not use control structures such as if,else,for,while,switch etc. (The answer is simple) (Don't cheat)
int number;
cin>>number; //get number
cout<<??????; //Your code53 -
Do NOT "compress" your code by leaving out braces in control structures and putting the 300 char statement on the same fucking line as the control structure!
Yes, your code file becomes vertically shorter than the usual 3000 lines, BUT my brain tumor proportionally grows larger.7 -
That moment when you thought you've fortified yourself with enough RAM for the future (32GB) and Blender fails to work with a large project because...it runs out of memory (just in the loading phase, building them intermediate data structures pushes it over the edge I guess).

It was kind of fascinating to watch the memory usage indicator creep up though. Morbid fascination.3 -
Just because you can learn HTML in a day doesn’t mean that you don’t need a degree.
Did you know that your browser, HTML, CSS, Javascript, and even your operating system use linked lists, binary trees, hash tables, and other so-called “useless” data structures?
It’s important to understand the roots and fundamentals of computer science even if you won’t use that knowledge day to day.
It changes your perspective on programming once you learn what actually goes on under the hood, and makes you think twice about the impact of what you write.
It’s relatively easy to get a programming job without a degree nowadays, but it often leads to web developers claiming that degrees aren’t important to their web apps.
There is much more than just the web to computer science, and that’s something to always keep in mind.10 -
Spend 14 hours a week studying more with my free time.
Things to be studied:
-discrete math
-data structures
-algorithms
-coding challenges
-problem defining
-abstraction
-other relevant maths
Other things I want to improve:
-confidence at work
-reaching out to teams with questions
-social skills
-time management
-enjoying the little things
-patience
-consistency (with everything above)
Last big thing would be being more conscious with what type of data/platforms I am digesting everyday. Just like a good diet I want to get in the habit of consuming “good” useful content that’s thought provoking or knowable rather than fast food social media carbs
Wish everyone a productive New Year!6 -

I cannot stand when they sugar coat their training and support structures in the interview then turning that into: We expect you to learn on the evenings and weekends as a “hobby”. My hobby is my choice not your choice otherwise it doesn’t mean a hobby, it means over time that you don’t want to pay for.15

Graduation day:
A guy presents a modified pathfinding algorithm based on a*, in Java.
Jumping to the conclusions, he says he tested the algorithm on a 128x128 graph based maze, but not larger because the program saturates his 4 GB ram pc.
One teacher (algorithms and data structures) literally jumps from the chair "you saturate 4gb of ram with a* on 128x128 graph?!"
Best graduation day ever lol9 -
Remove all the outdated and unwanted topics which were taught during Indus Valley civilization like: 8080 microprocessor, Java 6, Software Testing principles etc. And add more interesting and realistic topics like: Algorithm design, graphs and other data structures, Java 8 (at least for now), big data, Basics about AI, etc.7

My coworker doesn't know how to use a terminal. He talked himself into his position and instead of taking the time to learn about the basic commands he keeps asking someone else (including the teammanager, who's actually a software engineer) to do things for him.
For reference; we need the terminal to tail log files, keep track of processes, cron jobs, manipulate file structures, use scp (I use sshfs) to move things between other workstations and servers etc. Being able to use a terminal is one of the basic requirements for our job.
What.
Why.
How.

In my first year of college right now, and on the first test we had to write some C# ConsoleApplications. We got instructions of what we have to taken as input, what we had to do with it and output it to the console.
I've tested them all and they all work correctly, which was the main objective. I have used the correct data structures, but I didn't get top mark. Instead, I got lower because "I didn't do it her way".
WELL F*CK YOU TOO!!! I hope this is not how every test/exam goes6 -

Not learning data structures and algorithms. Not learning programming languages. Actually not learning anything to answer during a job interview.
I am more of a learn-while-you-do kind of guy. I never learn anything, instead just do it. Interviewers think I am useless because I know nothing. But I can get a job done, any kind of job done. I have no learning period, I can start working from first day in a all new language, in a all new IDE, in a all new OS.
I know nothing, and I learn nothing. I am a problem solver. You got a problem, I can solve it.6 -
If ever you felt imposter syndrome, it's after your senior experienced colleague rewrites an API you built... You've been chipping away at it for months, making it faster but reaching the limits of the functional but flawed original design.
In one week he starts it as a side project, and fixes the whole thing, soap to nuts... I need to sit down with that guy more.3 -
In my uni course "Algorithms and Data structures" we use Java. Fine. Definitely not my preferred language but it's not like I have a choice.
Anyway, our teacher uploads code files for us to use as reference/examples. The problem is, they look like this. Not only does she not indent the code, she also uses a charset that is not utf-8.
In the rare cases where she does indent the code, she uses THREE, yes THREE spaces...

The best teacher that I've had is one of the teachers at my university lab.
He teaches Data Structures. We had some programming assignments and I was good at it, but whatever I'd do, he'd always find bugs, ask me to resolve it and he'd always give me challenges in the lab which is fun in the lab environment. University labs usually sticks to the sylabbus. I actually learned alot from that experience..

I spent 4 hours finding a good way to instanciate golang structures. Came up with a function that returned a value or pointer and I just kept reusing the nomenclature for an entire project. Then my buddy looks over and goes, "Ethan, you're a f****** idiot", and shows me the standard nomenclature. Now I have to refactor my entire project. FML.

Anyone else taking Harvard's CS50 via edX? It's so awesome! You get a better understanding of Computer Science and stuff. I'm loving C! It feels so close to communicating with the machine. Memory allocation fascinates me, too. Is this why it's fast? If you feel like you're lacking with the CS fundamentals although you can build apps or websites already, I recommend this. This is better than my whole years in college!9

PM is such a fucking cunt
telling me that my data structures describing the layout of binary data would be confusing for devs, and that we shall introduce
typedef fuckingRetardedObfuscatingName uint8_t;
in our code. everyone is fine with the concepts i provide to describe this binary data, not only at our company but also in other software i've worked on and common standards i've worked with, we work like that and every fucking idiot knows what a uin8_t is.
you fucking braindead imbecile have no fucking idea how we work and you don't care, you don't even try to understand what we are doing.
god i hope you die being hit by a fucking bus or something8 -

For me the best of being a dev was described by Fred Brooks in his "The Mythical Man-Month":
...The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures....
Yet the program construct, unlike the poet's words, is real in the sense that it moves and works, producing visible outputs separate from the construct itself. […] The magic of myth and legend has come true in our time. One types the correct incantation on a keyboard, and a display screen comes to life, showing things that never were nor could be...

How I should approach a new project:
- think about data design
- draw some tables
- configure relations
- create data structures
....
How reality proves I'm a donkey:
- builds random table
- works on models, with random querys
- realizes things get to complicated and relations are broken or tables need duplicate logic
- starts thinking about 'good' design
- draw some tables
- configure relations
- create data structures

Game dev has never been more amazing. I am playing with different ideas for terrain. I want to modify terrain and build structures as part of game play. I thought about using a structure of my own to represent buildings and other structures. I got to thinking that maybe what I really want is voxels. So I decided to play with the Godot voxel plugin. I am looking at the "examples". Then I see this:
https://github.com/Zylann/...
"This is a 3D space game demo, with procedurally-generated planets." Wait what? I run the demo and I can fly to different planets and deform the terrain on each planet. This is a demo? Isn't this a main feature of NMS as a demo? Shocked but really excited. I can't wait to play with this.
Here is a screenshot from the demo:

First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.
Second year:
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.
Year three:
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.4 -
So after exactly 30 minutes of building a basic interpreter (yes I'm back on the interpreter wagon) in python, I have once again come to the conclusion that python can go fuck itself with its backwards and inconsistent syntax with needlessly over worked and backwards data structures...
Would rather work in fucking COBOL at this stage...3 -
"What app is that?"
"It's like yik yak for developers..."
"Like FML for programmers..."
"Like one big groupme for computer scientists..."
"Like Josh from Intro to Data Structures..."
I'm running out of ways to describe devRant.1 -
It was my first month as a driver developer fresh out of grad school, at a semiconductor company. There was an elusive memory alignment bug that had eluded the experts on the team. Of course, they had to assign it to me.
I was looking at the code where alignment was being calculated for nested structures case. I saw something funny: "size_t(object)". I asked the expert where it should have been "sizeof(object)". And, sure enough it was!!
I was super-thrilled to have fixed a bug in my first month, which had troubled the team for a long time! ^_^6 -

So I'm not sure I understand this question fully, if it is meant only through code, than I guess none or those people I got to know while I was doing my algorithms and data structures project last semester where we were helping each other with our code
If it's meant generally through code related activities then I gained lots of friends in uni in classes and here on devRant of course and actually yesterday I got to talk unexpectedly about coding and programming languages on an event with a guy who actually studied financial maths in Vienna but now works as a tester and works with databases, that was nice6 -
If there is 2 books you should read before trying to tackle TAOCP... this might be on it.. as well as the Concrete Mathematics book.
Anyway. This book covers not just the fundamentals of modern algorithms and data structures but it also makes the leap to understanding multithreading and algorithms using multithreading.
Some argue the certain concepts in this book are presented without explanation of how they work, but I guess that should be something the reader try’s to figure out from another book or constructive thinking critically. Keeps the reader on their toes for understanding.
This is also the reason many people suggest the sedgewick algorithm books, of which will be posted another day.

Finally after working on programming languages and Data Structures for too long developing my first software with a GUI. In python. 😀😀😀
Though its only a calculator for now. 😅😅😅😅3 -
Over the last year, I’ve only started learning computer science at uni, never done it before.
I’ve done units in:
- Alg. and programming fundamentals in python
- Intro to comp sci
- alg. and data structures
- theory of computation
Guess the point of this is, “why do people code, what aspirations do you all have?”
Cause rn, I’m all about “I have no idea what I’m doing, coding just seemed cool and I wanted to try it out.” Don’t know where to go
Someone inspire me???
Here is a legit reason for you to brag about what you do and what you’re going to do 😉13 -
Recently I launched the minimalistic online drawing app https://okso.app. I wanted it to be a place where people could do fast, ad-hoc, napkin-based-like explanations of any concept as if you are sitting with your friend and trying to explain him/her something during lunch. Don't ask me why it is needed, I was just experimenting.
So, the first concept I've tried to explain with sketches was the Data Structures. Without further ado, here is the interactive ✍🏻 https://okso.app/showcase/... showcase that you may play with.
Of course, not all data structures are covered. And of course, this is not comprehensive material, but rather a cheatsheet that would create visual hints and associations for the following data structures:
- Linked List
- Doubly Linked List
- Queue
- Stack
- Hash Table (with hash collision resolution)
- Tree (including the Binary Search Tree)
- Heap (including Mean Heap and Max Heap)
- Trie
- Graph
Each box on the sketch is clickable, so you may dig into the data structure you're interested. For example `Heap → Max Heap`, or `Heap → Min Heap`, or `Heap → Array Representation`.
The sketches are split into so-called Pages just to make it easier to grasp them, so the users stay focused on one concept at a time, they see the relationship between the concept, and thus, hopefully, they are not getting overwhelmed with seeing a lot of information at the same time on one drawing/page.
Each page has a link to the source-code examples that are implementing the data structure on JavaScript.
The full list you may find in the ✍🏻 https://okso.app/showcase/... showcase.
I hope you find this showcase useful and I hope it will be a good visual cheatsheet-like complement to your data structure knowledge.

Writing coroutines for io_uring. Submissions aren't working (they go through but the operation never seems to complete). Just fixed a few segfaults because of error cases not destroying coroutine handles correctly. Been on this for two days, finding more and more things I need to do that unrelated to the task at hand. Don't have issue tracking set up yet because haven't had time. Mountain of things that need to get working just for a demo is only growing. Layered maps of data structures and code flow are in my head as I'm trying to mentally debug some of this. I'm focused, completely dead to the outside world.
Then I feel a small scratch on my cheek. Three hours of mental mapping and a deep stack of thought, vanishes into thin air in a single moment.
The trade-off is worth it though.

If you're currently in college and wish to get placed in a major tech giant like Amazon or Facebook:
Don't learn React.js, instead learn Linked lists.
Don't learn Flutter, instead learn Binary search trees.
Don't learn how to perform secure Authorization with JWTs, instead learn how to recursively reverse a singly linked list.
Don't learn how to build scalable and fault tolerant web servers, instead learn how to optimally inverse a binary search tree.
These big tech companies don't really care what real world development technologies you've mastered. Your competence in competitive programming and data structures is all that matters.
The system is screwed. Or atleast I am.18 -
What I can figure out:
You give me a large application with multiple projects/classes/files/functions that is tens of thousands of lines long, I can debug it. I can picture the multi-dimensional data structures, objects that contain lists of other objects, all in my I head.
What I can't figure out:
Should I or should I not look at the person sitting at their desk when I walk back to my desk from the bathroom.4 -

ah this fucking sucks my boss, who is also the guy developing back end for our mobile app which im developing, isnt working on the back end makes me guess the fucking json strings that hes going to send and buils the front end, then later changes the fucking json structure completely and expects my app to work without any problems, how do you teach these fucking php developers the importance and significance of data types and data structures4

I work in a dev company. One of our clients hired us to help them out as their devs are failing with their deadlines.
I had to expose app services via an api. I did it. Client company devs didn't like the way I did it as I rewrote their datamodels and declared them as api-use-only. I was demanded to return bkend services' data structures.
I didn't agree and waited until deadline to submit my code.
Now they are honestly thanking me for what I did as I've saved them from a forever-mutating-api-and-angry-integration-customers hell.
Not sure whether should I be happy or worried. I forced my solution onto them. It's not proffessional. But yhe customer is happier now than it would've been.
What do you do in such situations?6 -
Did anyone heard about modular C?
I'm working on it at school, it's like how to do OOP in C with structures and function pointers.
We're developing the String class but next, we will make a basic C++ implementation in C before beginning the real C++
Do you think it's a good path?5 -
An intern approached me for help in one of their past exam questions. They said they had already turned in the exam but just wanted to know the answer. The question was not that hard and I had a bit of time to kill so I helped them.
Me: So, to make it O(n), you have to make it a double linked list, and keep a tail.
Them: But the problem requires us to solve it with a single liked list.
Me: You can just iterate it at the end to make it single-linked again. That costs O(n), so the solution is still O(n).
Them: Oh yeah right. I don't think we even need a tail though, we could just have a variable pointing to the last link.
Me: ...which is called a tail.2 -
Last night me and my friend were on a WhatsApp call discussing how we should practice algorithms and data structures more. We texted the logistics after and he sent me a calendar invite on google. I swear to god this morning I had adds talking about data algorithms all over YouTube but I have never googled this issue in the near past 🤔 this can’t be a coincidence...9
-
For starters this is my first post, found devrant the other day you're all hilarious.
I hate math, I hate proofs. I'm in a class "Analysis of Algorithms" and I have understood and do understand the importance of optimizing algorithms and data structures and I understand the algorithms and data structures themselves. That being said, I'm fucking sick of math and proofs and all this bullshit that is probably pretty important but ugggghh, I guess I just have to push through, but writing this out helped.14 -
This temporary hack will just temporarily fix this problem. We will come back and actually fix the problem later.
We never come back to fix it later. This shitty hack I made in less than a day that fixed the problem for the day "fixed" the problem for the next year.
Lesson learned that temporary structures and side projects will be there forever. Make them right the first time.1 -
I kinda hate to admit it but they were right. Data structures and algorithms are kinda the shit and you should try to learn and appreciate them. Not just so you’ll use them. But in that learning them helps you become a better problem solver.
There’s a self taught dev that my company works with for really bespoke applications. A senior dev that works with him and helps manage the development process told me that the dev in question doesn’t really know how to implement the finer details. Very telling indeed.3 -
Trying to switch my job. Applied for a well known company. Gave an interview today. I don't fucking get the obsession of these developer recruiters so fixated on data structures and algorithms. I know it's a massive part of computer science but guess there is no fucking room left to innovate in there. There are legitimate researcher teams working for implementation of these barebones inside system foundations. No general software developer gives a fuck about this piece of shit discipline of study. You wanna know why they propagate this as the panacea to test people because it's fucking easy. Give a project to somebody as interview procedure, it'll take time to bring out an interesting problem and an interesting solution to that. Sorry to say but all these data structure enthusiasts are nothing better than board game enthusiasts.
Also why can't you refer existing solutions to create your solution. I've seen some good problems which actually require you to think. But again those are heavy and can't be tested so you're left with reversing a fucking linked list with O(1) auxillary space. Fuck me ig.
Moreover, what the fuck is wrong with the moral policing internet crowd. Its so sad. I've hardly seen anybody rant about this piece of shit system put in place to push the absolute dead-end nutcases up the ladder. Every other search for it returns a Quora link with some Indian guy complaining about his interviews and in the comments you have the same scholars sitting in their data structure throne imparting knowledge about how data structure holds the fabric of reality together.
I don't hate data structures and algorithms as a subject. It is cool and quite extensive but once you try to make that as a metric of all the knowledge in the world, you've lost my drift. Maybe I'm just angry with the state of things. Maybe I'm just angry with token Quora crowd.4 -
Taught myself assembler at 13 (this was the mid 1980s) and wondered how the hell people could stand to do this. Then I found out there were more abstract languages like BASIC or COBOL. So I taught myself BASIC and MS-DOS batch scripting. Various other languages came later (PROLOG, Pascal, C, Smalltalk, C++, VisualBasic, etc). But it’s never been easy for me because I suck at math and complicated logic structures. Especially not good with OOP. My brain was ruined by learning procedural coding first. It refuses to incorporate OOP.
-
I just officially graduated from a web dev program and it feels...
Very underwhelming.
Learned ES6, React, Webpack, service workers, offline databases, accessibility, (...bla bla bla)
And my knowledge with data structures and algorithms isn't even that great yet.
I look at the stuff I still don't know and wonder if I'll ever be comfortable with my level of expertise.13 -
How many of you use the right data structures for the right situations?
As seasoned programmer and mentor Simon Allardice said: "I've met all sorts of programmers, but where the self-taught programmers fell short was knowing when to use the right data structure for the right situation. There are Arrays, ArrayLists, Sets, HashSets, singly linked Lists, doubly linked Lists, Stacks, Queues, Red-Black trees, Binary trees,.. and what the novice programmer does wrong is only use ArrayList for everything".
Most uni students don't have this problem though, for Data Structures is freshman year material. It's dry, complicated and a difficult to pass course, but it's crucial as a toolset for the programmer.
What's important is knowing what data structures are good in what situations and knowing their strengths and weaknesses. If you use an ArrayList to traverse and work with millions of records, it will be ten-fold as inefficient as using a Set. And so on, and so on.31 -
Do you get filled with anxiety and mental anguish when asked for your availability for a technical interview, knowing you’ve spent all your time recently programming and not working on algorithms/data structures and so you’re terribly unprepared but have no idea what the acceptable amount of time to schedule out without seeming like you’re incompetent is?
No?

Does anyone know what the **day-to-day** differences are between working in IT (banks, hedge funds) vs tech (Google, Facebook, Netflix).
In my mind, I see Hell and Heaven. And there's a giant wall in between called "technical interviews + algorithms and data structures".
I'm on the Hell side... And not sure if I should climb the wall 😔
Is the wall even that big?8 -
For the first time apart from Data Structures and Algorithms, there was a Machine Coding round where they asked me to create a small app using any language without data persistence or GUI, to see my code designing ability, LLD, code quality, whether I can implement OOP and write modular code and to see how extensible my code will be.
I did well.2 -
Don't forget to give the developers the opportunity to innovate. Nobody wants to sit and type out the same structures day after day. That's not why we got into this job. We like solving problems. In my current team we set aside some time every sprint to spend on individual innovation. Super useful as it gives us the chance to break out from the standard chugging of the backlog and spend some time trying to solve some of the trickier problems and bringing improvements back to the product that we discovered by messing around with stuff. If you are reading this and you are in charge of a development team, try this out for a sprint or 2.2

Gotta hand it to a faculty at my college. She is the best teacher, ever! Period.
She is pretty lenient, understanding, and always supports us and helps us.
She taught us Data Structures and the only thing that was bad was us students not giving as much effort as she gave to teach us.
She was so well that it always felt that we weren’t doing well enough.
Her subject was the only one in which every student passed!!
And still now, although she no longer teaches us, which hopefully changes next semester, I still love to go to talk to her about various things I do in programming and computers overall.
M just gonna say it...

Was working on my game engines scripting language for the terminal and this is how things went in roughly the space of 30 minutes
"Ok let's get a basic language structure defined..."
*Time passes*
"Ok, so now I have basic structure and concepts of a potential auto translation framework, external library use and just a dash of complicated file structures and use"
And I still haven't written a single line of code except for ignoring whitespace when starting to lex the file to transpiling ;-;2 -
Man learning I’m not good at learning new languages, I get to the point where I have the basics of the language ex: Conditional statements, loops, functions, classes, structures, file manipulation, etc but idk what to do after that, is this where I start learning libraries cause I still get the feeling I’m not at that step yet.
Before you ask, yes I know I am heavily over thinking this2 -

I just had a thought while thinking about Algorithms and data structures. Honestly other than for technical interviews I have never really had to use specific implementations.
Then I suddenly had a thought... What if I wanted to build my own operating system... I would also learn c++ as well....
I can't think of a reason to build my own OS though... Hm.. What about a programming language? Would that be like a mini-OS, and also need all this stuff?2 -
In a mediocre job since last 4 years with just a developer designation, but we simply use Java based tools and products to do most of our job. Need to study for a change in job.
Literally every morning:

What container data structures do all of you actually use?
For me, I'd say: dynamically sized array, hashtable, and hash set. (And string if you count that.)
In the past 8 months, I've used another container type maybe once?
Meanwhile, I remember in school, we had all these classes on all these fancy data structures, I havent seen most of them since.19 -
Here's my idea. In light of all the efforts to teach kids how to do programming, why not start with an introduction to discrete mathematics instead? From a lot of the programs I've seen, the kids are taught different structures such as if else, while, and for loops, but they don't attempt to start teaching them about recursive methods or even other structures such as linked lists, queues, dequeues, binary trees, heaps, different sorts, and other things. Am I just not looking deep enough into those programs? Or are the creators of these programs not wishing to cover those things because they feel like children wouldn't be able to comprehend such things?4

Just found this on Reddit
"I used to think that everybody should learn programming. When I first started learning –thinking about how to organize the world in terms of data structures and algorithms– I thought, "Wow, this is such an amazing way to organize information. Everybody should learn to do this!"
I don't think that anymore.
I think there has to be something seriously wrong with you in order to do this work. A normal person, once they’ve looked into the abyss, will say, “I’m done. This is stupid. I’m going to do something else.” But not us, ‘cause there’s something really wrong with us."

I've always been wondering why do tech companies need everyone to have a strong grasp of algos and data structures?

so in my city there's an opportunity for some
tech university students to attend extra programming classes for a year (12 hours/week). they'll teach many things: (advanced) data structures, databases, oses, computer networks, compilers, making games, data analytics etc. is it worth attending or i should just write down those topics in a to-do list and learn them by myself? i've never attended such courses so i don't know if they are useful or not. thanks for taking the time to read this :)6 -
Teach data structures by showing how they're used in real life situations. Don't make us do some nonsense puzzle shit. For example, a friend of mine is learning stacks/queues right now and his assignment is to build a simple HTML parsing algorithm to determine whether an HTML file is valid. This shows the student a practical use of the data structure and reinforces that this shit actually does get used in real life.

Hello everyone !
I am a self taught programmer. Currently in last semester in electronics engineering. I want to become a software developer but can't decide the right career path for me to take. I like back end, Android, Data structures and algorithm, Parallel programming, Machine learning and computer vision, and even security. I am afraid I will remain the jack off all trades and won't be the master of any. This way I won't be doing any good in my career. Any advice as what to do ?7 -
When I started uni and I took my first programming subject (Data Structures) I hated it as much as I could. My teacher was a complete @$$hole, he wasn't good at teaching, and most people were failing the subject. When I finished that semester I swore I would never be a programmer...
11 years later and I have a Master's in IT and have been working as a Software Engineer for 6+ years. #life
I wish I had a better experience learning the basics1 -
This was in 1st semester and our CSE course went under some major course revision. Python was to be taught in place of C. Now the professor we had was very famous and we were excited to be in his class. But little did we knew he had no knowledge of Python at all. He used to tell the lab assistant to teach.It was so bad that I lost all interest in programming!!
But we all studied python later in our winter holidays for further courses.
Next semester we had OOP and this is what happened:
1st lab:
Professor(different): I expect you have basic knowledge in programming so I have uploaded.
Every question was related to structures in C.
In the same semester, we had data structures where we were 'expected' to know C or C++.
Later we came to know that Python was not going to be of any use in any course ! First semester went into dustbin.

It was pretty long rant. Hope you didn't get bored :P

Don't you guys think we need live programming?
Like a development runtime, instead of doing this whole file based development thing? We edit files, and then run them, why aren't we just running a program constantly and editing it as it runs? It would let us inherently take advantage of concepts like objects and lists instead of having to build plugins that analyse and modify our files to sort of act like complex programming data structures.
If we just programmed using these complex data structures to begin with.
Like do you realise how antiquated the idea of a file is, and folder, that's literally a paper based analogy.
Imagine if we just had objects, with pointers and property names, the best we have is ln -s file1 file2 but that's not a real pointer.
Anyway, hope someone understands me!
I'm writing a medium article called a world beyond files but I'm stuck at how low level to go and who the audience of the article should be.
I went really in depth into what this idea of an "object" is, and how it can be expressed in a file but once a program picks it up it becomes much more and almost alive.12 -

Best way to deal with office politics?
As background: we have our own implementation of some C++ data structures, including an "Array" class (basically the same as std::vector).
A few years ago, the senior guys on my team refused to add new features to it for (seemingly) no good reason.
So senior guys from another team added the features anyways, in THEIR repo.
My team couldn't stop them, but refused to allow the new features in OUR repo, so now our Array is split between two repos for no good reason 😢.
Two years later, here I am, hoping to clean this up. As far as anyone knows, there's no good reason to have it split up like this.
How do i convince my team that we should move the code to OUR repo where it belongs?7 -

Hey guys and girls, quick question.
Im currently writing my own collection-framework in Go.
It has a Collection-Interface, that looks like this:
Clear()
Size() int
ToSlice() []interface{}
Add(...interface{}) error
Remove(...interface{}) error
Contains(...interface{}) (bool, error)
The library should also contains stuff like stacks and queues, so datastructures, that dont fit that interface perfectly.
So should i write a weird implementation of the interface for them, like Remove for stacks (high pitched internal screaming), or should i just say fuck it, and dont implement the Collection-Interface for these specific types ?3 -

Playing pokemon. I'm extremely into the series and played nearly every gen since the first ones. Even bought the cheap 2ds just to play these 3ds versions even tho i got acutally no time during exams and sometimes even played the different editions of the same gen just because i can.😅
And I have the habit to think about "how is it done?" With everything that is displayed on a screen or just blinks. And with 800 pokemon and their stats and subforms and IVs and all that nerdshit (back then compressed in such a small rom and running on pretty low end devices) i began to think about data structures, organization of them and such, especially when there are many big, wide datasets.😪3 -
Oh god, structure alignement, why you do this... You might be interested if you do C/C++ but haven't tried passing structures as binary to other programs.
Just started working recently with a lib that's only a DLL and a header file that doesn't compile. So using python I was able to use the DLL and redefined all of the structures using ctypes, and the nice thing is: it works.
But I spent the whole afternoon debugging why the data in my structures was incoherent. After much cussing, I figured out that the DLL was compiled with 2 bytes packing...
Packing refers to how structures don't just have all the data placed next to each other in a buffer. Instead, the standard way a compiler will allocate memory for a structure is to ensure that for each field of the structure, the offset between the pointer to the structure and the one to the field in that structure is a multiple of either the size of the field, or the size of the processor's words. That means that typically, you'll find that in a structure containing a char and a long, allocated at pointer p, the double will be starting at p+4 instead of the p+1 you might assume.
With most compilers, on most architectures, you still have the option to force an other alignment for your structures. Well that was the case here, with a single pragma hidden in a sea of ifdefs... Man that took some time to debug...2 -

Hey DevRant!
Not really a rant but a question:
I just got accepted into a coding bootcamp. Have any of you been involved in one? How was it? What would you do to make it a better experience throughout? Any advice or suggestions?
It's full time, six months long and I start in October and I want to make sure I make the most of the experience and absorb as much as possible.
I'm super happy that the course appears to be less just learning JavaScript and more involved in the Computer Science side of things, even including bits about C/C++, distributed systems, algorithms and data structures, software design/testing, cryptography, database management, and computer architecture. It also, of course, covers tons of resume work, interview practice, and networking.
Thanks!5 -
As a Software Design junky, I just enjoy using TypeScript for more conventional C-style programming structures in JavaScript !2

How can Javascript, one of the MOST WIDELY used and MATURE languages with A MILLION CANCEROUS FRAMEWORKS, NOT have a basic collections class? Are data structures not important in Javascript?

Not so much a problem with the way CS is taught, but I think it's a problem that a lot of people put emphasis ONLY on programming (and maybe data structures and algorithms) and ignore things like Computer Architecture or Theory of Computation.
Most of the CS syllabi I've seen are built very well, but many students (and some teachers) seem to ignore a bunch of subjects because they don't contribute to making them "hireable". -

I learnt Java in 2 months from 0 (or 0.005), a year before going to college. (the full experience™️; not just String, while and sysoCtrl+space)
On "Data Structures and Algorithms" class, the teacher says something like "usually OOP takes like 2 years to learn completely".
Me in my mind: "Aaahh I'm so proud of myself. *selfhugs*"
Of course I knew the teacher was exaggerating but even if she doubled what she thinks, I still was in the cool range. B|3 -
I've been given a huge stack of paper, some users stories and loose specs. Was tasked with engineering the specific requirements, then the models and finally the database. Then I need to build an API on top of that.
Stuff I'll use is Go and Postgresql. Small issue is, I've never done DBs, so I've no idea what to do or where to start.

I decided I am going to get full into Minecraft modding. It will be an opportunity to learn Java and Kotlin. I want to explore some game ideas in a well defined sandbox.
Some things I want to explore.
1. AI that helps you build and survive. This fascinates me and seems like it could be a good challenge. I like the idea of learning how to separate structures into chunks. I think I will learn a bit about tree data structures here. Maybe learn something about BSP trees (if applicable).
2. The idea of an RPG quest system tacked onto a sandbox. I want to spawn structures and create non-repetitive story lines. Minecraft can be really desolate if you are not playing on a server. Worlds tend to be empty and devoid of story.
3. Maybe try a hand at terrain gen. This could be fun to explore entropy math. It is fun to draw things with math.
I am sure I will come up with other fun things to explore here.9 -

Perhaps as a tip for the junior devs out there, here's what I learned about programming skills on the job:
You know those heavy classes back in college that taught you all about Data Structures? Some devs may argue that you just need to know how to code and you don't need to know fancy Data Structures or Big o notation theory, but in the real world we use them all the time, especially for important projects.
All those principles about Sets, (Linked) lists, map, filter, reduce, union, intersection, symmetric difference, Big O Notation... They matter and are used to solve problems. I used to think I could just coast by without being versed in them.. Soon, mathematics and Big o notation came back to bite me.
Three example projects I worked in where this mattered:
- Massive data collection and processing in legacy Java (clients want their data fast, so better think about the performance implications of CRUD into Collections)
- ReactJS (oh yes, maps and filters are used a lot...)
- Massive data collection in C# where data manipulation results are crucial (union, intersection, symmetric difference,...)
Overall: speed and quality mattered (better know your Big o notation or use a cheat sheet, though I prefer the first)
Yes, the approach can be optimized here, but often we're tied to client constraints, with some room if we're lucky.
I'm glad I learned this lesson. I would rather have skills in my head and in memory than having to look up things and try to understand them all the time.5 -

My company boss wants to reorganise the team structures drastically.
Currently we have different teams for each product. And in that team we have a lead, frontend and backend developers working in sync.

I acknowledge that I didn't know how to program until I was in 5th semester at my second try on data structures.

I am preparing for InoI( Indian informatics Olympiad ). Any tip would be helpful. I am gonna use Java. What algorithms and data structures should I focus on ?4
-
1. Teach DS and Algos. Not basics but advanced data structures and the ones that are recently published.
2. DBMS should show core underlying concepts of how queries are executed. Also, what data structures are used in new tech.
3. Teach linkers, compliers and things like JIT. Parsers and how languages have implemented X features.
4. Focus on concept instead of languages. My school has a grad course for R and Java. (I can get that thing from YouTube !!)
5. Focus a little on software engineering design pattern.
6. It's a crime to let a developer graduate if he doesn't know GIT or any version control. Plus, give extra credits for students contributing to open source. Tell them if they submit a PR you get good grades. If that PR gets merged bonus (straight A may be ?)
7. Teach some design pattern and how industry write code. I am taking up a talk at school to explain SOLID design pattern.
Mostly make them build software!
Make them write code!
Make them automate their homeworks!
Make them an educated and employable student.!1 -

TL;DR: What do you hate about the current interview process for software dev positions?
I have been reading interview related posts on reddit and other places and I have noticed that there is a lot of hate, especially from more senior devs, towards the typical software dev interview pattern i.e. the one focused on algorithms and data structures and I don't understand why. The current methods may be far from ideal but I think they do a good job of eliminating the false-positives. Plus, I can't think of a better alternative. Sure, by using current interview methods some good devs might get rejected because they haven't used/needed/studied many algorithms and data structures after they left college, but for any big company that gets thousands of applications every year, that wouldn't be a big issue compared to the negative impact a false-positive may create. I am still in college so I maybe biased, I would like to hear your thoughts on this.3 -
I just learned C and I have created some projects like Parking System and Library Management System. My problem is I don't know mathematics and I want to learn DataStructures & Algorithms and become pro in it. In the whole September I will still be focusing on C and create more projects. I have started learning Mathematics today from High School level to College level. I thik maths will take 1 year to complete. After September in the October I want to start learning C++ and finish C++ till the end of Dec 2019. I want to know that do I have to first finish my maths learning which will take 1 year then I should start learning Data Structures and Algorithms? As I said I want to become a professional in Algorithms. I think its not possible to learn DS&A yet I have to wait 1 year till I finish learning my Maths. I can't do more with C & C++ without knwoing DS&A? If I started learning DS&A with C++ in the future then I can't become good at algorithms? I want to do competitive programming and be at Top 1 of Hacker Rank and other sites like this.7

I called it the ETL, for easy template library (like the STL was hard!!). Thats when i knew i had a knack for it and began really learning.

So, our lab professor in university for data structures was evaluating my friend's group assignment next to me and my colleague.
Professor: So, what does this method do?
Friend: I feel it would be best to explain our structure first and then how our methods work.
P: No, no. It's okay, I'm seeing it here in my laptop. *Looking at their report which included nothing about the structure of the assignment since she asked specifically only to place the methods and their complexity analysis due to not having time to look and evaluate a full report for each group*
F: Okay, *proceeds to explain*.
P: Okay, and why is your code commented?
F: Because it's good practice and we learned in subject x last semester.
P: Impossible! I teach that subject and I did not teach that in my classes.
F: Okay, but our professor did.
P: *Says nothing*.
They got a 3.25/5 as a grade for it and got really pissed off. I mean, they spent a lot of time making the assignment's structure perfect, optimizing their code and the professor did not care for the structure, just the methods, on the data structures subject.
FYI, they are workaholic, dedicate a lot of time improving their skills and their normal grades are usually >= 4.25.2 -

Who else was fascinated by the DOM when first encountered? When I first began my journey as a programmer I found that the term Technology was always set in strictly a physical sense in my mind; that is until I started to realize that every language is in fact a piece of technology, which is supported by massive libraries. Then I realize that the DOM is another standardized technology that structures the web. And of course as I gained more insight and got introduced to more "technology" the clearer it became. I'm just glad we have so much selection in terms of this technology. Whether it's a language you want to use, a particular OS, Vm, framework or the plethora of others begging to aid and assist.

I hate data structures. I try to work out their algorithms in my head but they're completely counterintuitive. lol.8

I think professors should relate computational processes to mathematical ones more often. This helped me out at the beginning a lot when learning CS through the internet during high school.
I remember that a lot of the computational logic made sense to me because of math.
e.g. functions, comparators, variables, for, and, xor, sets, trees, sorting, searching etc.
A lot of these topics are hard to teach for beginning computer scientists. But I think if professors made the relationship with math from the beginning it would be easier for the students
I dont know if teachers already do this but the first time I had a professor relate math to code was while taking data structures in my second year of college1 -

Hey, Do you think it's common to get an interview take-home test like this...
Write a Python script that:- Downloads the Equity bhavcopy zip from the above page- Extracts and parses the CSV file in it- Writes the records into Redis into appropriate data structures(Fields: code, name, open, high, low, close)
Write a simple CherryPy python web application that:- Renders an HTML5 + CSS3 page that lists the top 10 stock entries from the Redis DB in a table- Has a searchbox that lets you search the entries by the 'name' field in Redis and renders it in a table- Make the page look nice!
Commit the code to Github. Host the application on AWS or Heroku or a similar provider and share both the links.14 -

DEVIANTS!! NEED ADVICE...
I have been focusing on learning and implementing data structures and algorithms through participating in competitive programming sites...
Whenever I face an issue and struggle to find an answer (which is more often than not), I ask the forum about the fundamental principles involved in the question...
I avoid looking at the solution, as much as possible.. And, when I do look at them, I still question the author of the code about the reasoning behind a particular section of code which I don't understand...
I don't wish to copy and paste code, but sometimes, I wait for days on end, but I don't use the code until I receive an answer...
Is this the right way or are there any other way which I could implement to strengthen my algorithmic thinking??10 -

My time management skills are abysmal. I am in my senior year in school and a few months back decided to appear for the informatics Olympiad. So now I am reading a book on discrete math, while reading books on algorithms and data structures. I code every day for around two hours. I have my math syllabi in school which is all calculus. My physics syllabi consists of all of EM and Optics along with nuclear physics. I haven’t touched chemistry since the beginning of this year. I try to give a considerable amount of time to math and physics because I f***ing love studying those. But doing that means slacking off on the Olympiad stuff. I am completely overwhelmed. My midterms are two weeks away and I am so unprepared. I am really clueless on how to manage time. -
In my university there was a programming teacher who taught the basics "algorithms and data structures". This was the first subject about programming ever.
He mostly just showed us the idea behind each and sometimes showed a slide of an algorithm or data structure in C. He was also supposed to carry out lab classes where he would teach us the basics of C.
Guess what?
He thought that programming could not be taught in class but only self learned... so he didn't do a single computer lab class the entire year. The rate of students who passed his subject the first time was low. We ended up talking to the dean and the teacher was given an assistant for the lab classes the next year. Fun right?1 -
Let's see.
1. Scott Meyers.
He has a gift at teaching. Easily simplifies and structures complex concepts into memorable bits. And he has that charisma/strategy that you could watch/read any of his presentation/tutorial without prior context and it would still be interesting and fun (and of course improves your understanding on that topic).
2. My trainer at the first company I worked at. Fantastic guy. He would never answer a question right away. He would take a minute, go on to explain an abstract concept and then sort of derive the answer to the original question. Always, towards the end, we would be beaming at each other. I, because the answer would 'click' just before his reveal and him, because of the joy that his explanation worked.
He also emphasized working with the absolute minimal examples just like Meyers. -

The NPC has stated that the personal data of atleast 2000 people was leaked after the attacks on the websites of the philippinian goverment on april 1, the data contains; names,adresses,passwords and school data.
Over 7 administrators of schools, universities and other goverment structures have been called out for not reporting on the leakage of personal info on public facebook groups and violaton of the NPC in under 72 hours.
The representatives of the next structures stood before the comission on the 23 and 24 of april
- Taguig City University
- Department of Education offices in Bacoor City and Calamba City
- the Province of Bulacan
- Philippine Carabao Center
- Republic Central Colleges in Angeles City
- Laguna State Polytechnic University
The agency has reported that none of the organisations had notified about the personal info leakage yet.
This is a good reminder that you should inform about security/personal info breaches everyone that might be related to it as soon as possible, even if it seems unecessary. -

C++ / OOP QUESTION
I have a uni assignment / project (Data Structures class), where I have to implement the ins-n-outs of 1D arrays, by creating a dynamically allocated array class, which can accept any type of data (using templates). But there's a problem.
I'd like to implement sorting the elements of the array. But given the fact, that I'm using templates, I cannot treat the elements as integers, nor as strings, or other types...
Also, let's say that the elements of the array are elements of class T, where T looks like this:
class T {
private:
double height;
int age;
string name;
public:
double getH() { return height; }
int getAge() { return age; }
string getName() { return name; }
};
(It's just a random example, pls don't judge for code quality...)
Let's say that I'd like to sort the T elements based on height, print out, sort by age, print out, then sort by name and print out. How can I do this? Is this possible?5 -

!rant (I got down voted for this on Stack Overflow, so I try to discuss the issue with a more professional crowd.)
In a Software Engineering class, we had an assignment to read Parnas' seminal paper on modularization [0]. In this paper, two approaches of dividing a software into modules are discussed:
Traditional Approach: A flow chart is drawn to work out the single processing steps and the program's high-level flow. Then every processing step is turned into a module. This approach doesn't yield very good results.
New Approach: Every design decision will be turned into a module by the means of information hiding. This approach leads to much better results.
My personal interpretation of the term design decision is that the modules are identified as data structures rather than as processing steps of an algorithm. This makes sense, because data structures are much more suitable for information hiding then processing steps of an algorithm. (The information inside a data structure is hidden behind functions, whereas a function only hides more detailed processing steps and no information; the information is actually passed in as arguments.)
Why does the second approach work so much better than the first approach? Here comes my second interpretation: The single processing steps of an algorithm are not replaceable (and thus not reusable), whereas it's possible to convert data structures into other data structures.
And here's my question: Could that be the reason why software development using workflow engines (based on BPMN, for example) never really took off?
My personal experience is that the activities created in such workflows are hardly ever reused, but there often are big data structures passed around all the involved activities, even if most of the activities use only one or two of them.
My question exaggerated: Could we get rid of all those clumsy workflow engines by giving managers Parnas' paper to read?

So at the moment, I'm currently reviewing the API specifications that got written up as the other developers haven't bothered to update it themselves. When you think about it, that's kind of dumb. If you are in charge of a particular function, it should be your responsibility to maintain documentation.
Anyway I'm cross referencing to what I see that has been done in the source code and finding way too many inconsistencies across specifications and implementations. Even parts where they have the exact same data, the structures are completely different. Or some parts have been documented but are not in the implementation, or vice versa. SO I can't tell which is the correct one! -
- Dictate the user experience of the product
- Get it built automatically by IDE - backend, frontend, whatever, everything.
- Customizability options - make changes to UI, backend structures, database schemas and models
- all of this by just talking in normal human language. -
I think I may have just had a bit of an epiphany...
Algorithms and Data Structures are sort of like libraries and frameworks.
JS is probably the easiest example since npm has a lot of libraries.
For most cases, underscore.each and lodash.each $.each achieve pretty much the same thing except one maybe better in certain cases.
And data structures are sort of like Angular, React, Electron, ReactNative. Each has its own purpose or style and are good for solving certain types of problems?
So day-to-day you don't really care what Sort() algo you use.. unless you really need to perfoarmance tune it for a specific case.
And data structures, depending on the type of problem you have, one is easier to work/think about the problem in although not examply... Usually have to use a few of them at once.
How is this going to help me in interviews... I'm not sure... other than reconfirming that knowing specific implementations of Sort and Trees is usually BS... most of the time just need to know you should Sort or use a Tree... -
GitHub is down. Unlucky client, guess I have a *really* good excuse not to push that scope-creeped heap of a new frontend. Because apparently 'those "small changes" you've made to the Sketch file are in fact entirely new uses of the data structures' wasn't good enough.

How many of you have formalized knowledge in computer science theory? Do you find yourself using that knowledge in your daily engineering life? For example, knowing random search algorithms, or obscure data structures. I ask this because of the modern "technical interview" trending towards discrete math instead of actual programming ability. Instead of coding projects I care about or reading research papers, I'm just doing discrete math problems to prep for recruiting. While it's not the worst thing to do I just wish there was a more direct way of interviewing a person's engineering abilities.1

When do the front-end developers get the APIs.?
How does the communication between front-end and back-end works.?
I work in a startup and I'm getting the feeling that this communication is way off the place. Many-ier times we have to wait for weeks for the API to come. Till then, we build mock data structures and implement it. The API gives us more and less exactly what we need. And you can guess it sometimes the structure gets changed in such a way our front end code gets to be refactored.
Is it the correct way.? The whole mock data structures and wait for the API thing. One of my colleagues says, "It's much better if we get some part of API first and integrate it progressively".2 -

Since I lack proficiency in Object Oriented Analysis and Design and Datastructures and Algorithms and this has caused me many problems at work, I must review these.
You'd think you don't need to know the 'dry theoretical matter' as they say, oh but you do.. I found out first hand at one of my tougher programming jobs where you have to create everything manually.
And now, looking at my entire first and second year of university courses regarding this matter.. the amount I have to study is enormous. Datastructures and algorithms alone: 1000+ page book + 500+ slides.. and that's only fresh man year! Yep.
I could say there's a way around it but.. I don't really think there is. If I keep just knowing the basic programming concepts, I won't get far. I need to dive deeper.
Until I master this material, it will keep haunting me in programming jobs.

Where can I find those types of "homework assignments" where let's say a company sends you a sample project and asks you to add few features where in that way you learn new technology in a practical way?
I know there are some public "homework assignments" projects from Wix where you're given a sample project that uses let's say react framework and typescript where you have to learn react and add features and send it.
These projects IMO are the best way to learn new technologies fast instead of going through the documentation and figuring wth are they talking about before you realize the full potential.
Are there any of those "awesome lists" in GitHub or something? No I'm not talking about "algorithms and data structures" type of thing, I'm talking real practical samples that I can learn from and extend it.1 -

THIS is powering the internet:
"[...] was a protocol number, similar to the third argument to socket today. Specifying this structure was the only way to specify the protocol family. Therefore, in this early system the PF_ values were used as structure tags to specify the protocol family in the sockproto structure, and the AF values were used as structure tags to specify the address family in the socket address structures. The sockproto structure is still in 44BSD (pp. 626-627 of TCPv2) but is only used internally by the kernel. The original definition had the comment "protocol family" for the sp_family member, but this has been changed to "address family" in the 4.4BSD source code. To confuse this difference between the AF_ and PF_ constants even more, the Berkeley kernel data structure that contains the value that is compared to the first argument to socket (the dom family member of the domain structure, p. 187 of TCPv2) has the comment that it contains an AF_ value. But some of the domain structures within the kernel are initialized to the corresponding AF value (p. 192 of TCPv2) while others are initialized to the PF value."
